IBT, I had not heard that before.  It was my understanding that homo sapien was different from other two-legged humanoid forms such as perhaps cro magnon man.  And I have seen something which I think suggested that the two lived at the same time.  It was also my understanding (from a documentary I think on Nova) that DNA research has pin-pointed man's origins in Africa, and from there he wandered to different continents. 

Trying to think back to the documentary, I think it was discussed that when he left Africa, he did not make a straight line to Europe but I believe followed the southern coast for some time.  Somehow some groups kept this up and continued on their way to Australia, which may have been connected to Asia at one point.  Another group continued up through the Mongolian region and across the Bering Straight on their way to North America.  Somewhere during this time some made their way westward to Europe, but at which point I do not recall.  This theory was based on DNA or blood charting.  A scientist tested people at various geographic points and was able to determine, based on their biological blueprints, how manking likely traveled across the continents.Of course one of the questions that then arise is how different races evolved.  Evidently the group(s) that went northward to Europe lost their need for dark pigmentation (due to climate) and they eventually evolved, over many generations, into people with standard Anglo traits of today.
